My data is like

i got it this tool only support hourly data

There's a log file in /api/log/curve.log

For me the error message implies a python 2.7 / python 3.x issue - it's using string operations on a byte array. I suspect in order to get this working properly you need to create a venv with the correct package versions (i.e. looking at api/requirements.txt the minimum required versions are quite old and installing the latest probably causes issues)
